RELATED APPLICATIONS

The subject matter of this application is related to Chinese UtilityModel Application No. 2021219253271, filed on 2021 Aug. 17, and U.S.Provisional Application No. 63/113,401, filed on 2020 Nov. 13, all ofwhich applications are incorporated herein by reference in theirentireties.

BACKGROUND OF THE INVENTION

Soft personal-use salves or sticks such as deodorant or lipstick aretypically packaged in a tube body. Typical packaging, however, does nottake into account the risk of easy access by children. For example, theupper cap of a deodorant tube is typically an ordinary removable cap,which can be easily opened by children. A lower cap on a deodorant stickis typically not secured, enabling that children can easily pull it out,thus there is a risk of the contents being exposed, abused, and/oringested by children. In addition, existing tube bodies are typically asingle-layer structure of ABS material, not environmentally friendly fordirect contact to the internal product. The product is also often indirect contact with the upper cap, which can cause contamination of theproduct between uses.

SUMMARY OF THE INVENTION

This disclosure relates to the technical field of packaging for a stick,topical or salve personal product, such as deodorant, which has safetyfeatures to prevent access by children. Disclosed is a safe container toprevent children from opening in view of the shortcomings of theexisting technology. The container is featured by good structuralsafety, inaccessibility for children, and ease of use.

In one embodiment, a child resistant deodorant stick container can beused for the legal cannabis industry where people have topicals andsalves that are applied to certain areas of the body, such as the elbow,to ease pain. This stick container can be implemented using a “line upthe arrows” mechanism, quarter turn opening mechanism, or other childresistant functions, all covered in this application. By quarter turn,we mean a child resistant function where you push down and turn aboutone quarter of a full turn in order to then lift and open, versus manyother child resistant functions which turn 360 degrees and you push downand turn. The quarter turn allows for the deodorant to not scuff whenopening, as may be the case with line up the arrows versions if theconsumer does not twist the stick down each time they use the product.It is better to adhere a tamper evident label or other tamper evidentpackaging to quarter turn versus line up the arrows, as line up thearrows rotates and may break the tamper evident seal even before thepackaging has been opened. The container allows for a quarter turn,while still being flush on the exterior. This is important for not onlythe look, but also for the ability to automate filling and also applylabels. If the cap is larger than the base, it can look like aflashlight and be very ugly and will hurt the ability for the product tosell. The deodorant stick container has a lower cap which, once it isattached, cannot be removed, but still works in automation systems. Thisis important because during child resistant testing, if the childremoves the bottom, that may be considered a fail.

In one embodiment, a deodorant tube comprises a bottle body, an uppercap component, a lower cap, an inner liner, a rotating component and adiscardable cover, wherein: the upper cap component comprises an outerupper cap and an inner upper cap. The inner wall of the outer upper capis arranged with multiple sets of bayonet lock structures along thecircumferential distribution. Each set of bayonet lock structuresincludes an upper bayonet lock and a lower bayonet lock. The inner uppercap is arranged with multiple convex elastic pressing pieces along thecircumferential distribution. The side wall of the inner upper cap isarranged with a plurality of upper clamping slots matching the upperbayonet lock along the circumference, the upper side of the bottle bodyis arranged with a plurality of lower clamping slots matching the lowerbayonet lock along the circumference, and a chute for the lower bayonetlock sliding is formed between the adjacent lower clamping slot. The toppiece is sealed with the inner liner, and the bottom of the rotatingcomponent is connected with the lower cap. The deodorant tube structureof the utility model has good safety, and the upper and lower caps arenot easy to be opened by children. And the bottle body adopts adouble-layer structure, which can avoid the deodorant from beingpolluted and can be used normally.

A safe deodorant tube to prevent children from opening is provided,comprising a bottle body, an upper cap component disposed above thebottle body, a lower cap disposed below the bottle body, an inner linerdisposed inside the bottle body and a rotating component for ejectingthe deodorant, and a discardable cover disposed above the inner liner,wherein: the upper cap component comprises an outer upper cap and aninner upper cap, the inner wall of the outer upper cap is arranged withmultiple sets of clamping convex structures distributed along thecircumference, each set of bayonet lock structures along thecircumferential distribution; each set of bayonet lock structuresincludes an upper bayonet lock and a lower bayonet lock; the inner uppercap is provided with a plurality of raised elastic pressing pieces alongthe circumferential distribution; the side walls of the inner upper capare provided with a plurality of upper clamping slots matching with theupper bayonet lock along the circumferential distribution; the upperside walls of the bottle body are provided with a plurality of lowerclamping slot matching with the lower bayonet lock along thecircumferential distribution; and a chute is formed between adjacentlower clamping slot for the sliding of the lower bayonet lock; thediscardable cover is hermetically connected with the inner liner, andthe bottom of the rotating component is connected with the lower cap.

The elastic pressing piece can be set in one body, contacted with theinner wall of the outer cap. The bottom of the liner is formed with acircular clamping slot, which clamps with a circular clamping slotformed in the inner wall of the bottle body.
